To all whom it may concern of Ohio, have invented certainnew and use-f ful Improvements in J Clamping Devices for Demountable Vehicle-Rims, of which n the following is-a specification. h

My invention relates to improvements in means for holding tire-carrying; wheel rims in position, and particularly to aclampingdevice for such wheel rims which permits a rim to be quickly removed and replaced.

' The object-of the invention is to provide a simple and reliable device for this purpose' which allows thewheel rim. to be removed and replaced iwith a minimum ex? penditure oftime andllabor. y

In an improved embodiment of my invention I employ a tire-carryingrim having; a pair :of linolinem faces on its inner side, these faces converging inwardly ;or toward the center of the wheel. 1 The folly rim is provided with an inclined. seat whichem gages one of the inclined faces of the tire carryingrim, while the other inclined face is engaged by a movable retaining member which is held in position by means of a clamping member which is made movable toward and away from the center of thewheel and which, when in its outermost position, overlaps the retaining member. The clamping member is moved, and retained in either its inner or outer position, by a;cam-' carrying member which is rotatably mount--' ed on the side of the fellyand may be turned by means of a wrench or other suitable tool. In the accompanyingjdrawings Figure 1 is a cross-sectional view of a portion of the telly of a wheel carrying a demountable rim. the folly being provided with my improved means for retaining the rini' in position. In this figure the retaining cam is shown in the retracted or inoperative position; Fig.; 2 is a side elevational view of thBHSfiHlB parts as are shown in Fig.1; Fig. 3 is a view similar to Fig. 1', but omitting the tire and. showing the retaining cam in the. opera-f tive position; Fig. 4 is a lside eleva'tionali- Specification 0t Letters Patent.

l i rim isxthe tire-carrying rim 12 which may be provided with the inturn tire. The at opposite edge of the tire is which is held in position by a retaining Iring turned lip 17 which is formed on the tirecarrying rim -12.v

The inner face of the tire-carrying rim 1-21 is formed with a pair of inclined faces or seats 18 and-19. These seats converge inthe face I? being engaged by acorrespond- 'ingly inclined seat 20 on the felly rim. It

consist ofa ring, preferably of suchcross sectional form as to afford an inclined seat for engagement with the inclined face 190i lip l3for grippingithe retaining ear 14 of a'fclencher gripped by a tire-engaging member 16! 16, the latter being held in place by an upwardly or toward the center of the wheel,

will be seen that if the tirecarrying ri'm he slipped onto "the wheel from the right hand provided a retaining member 21,.which may this member engages a face 22, preferably,

inclined, on the felly rim.

To. hold the retaining member 21 in position, there is provided a series of *clamps,

spaced at equal intervalsaround the felly of telly and has its head 29 .formed to engage: one edge of the telly rim 11. w The opposite end of this bolt is threaded to receive a member which comprises a nut 30 and cir-i cular cam 31 formed integrally. Thec am portion 31 of this member occupies a demember 23 andengages the ends 32 and 33 of this depression as the nut 30 is rotated b means-of, a wrench or'other suitable "too be..reciprocated toward and away from the center of thewheel. .-member is in it's outermost position it overthe wheel on whichismounted the flkyfim': l1.

or replace the samerim with a new tire which causes the cam portion 31 to move -the clamp 23 inward or toward the center of the wheel and out of .engagementwith the retaining member 21. Thelatter {may then.v
